The Stardust probe has returned to Earth, riding down from the sky on a pillar of fire after a voyage of almost three billion miles to land with remarkable precision on a military base in Utah. Aerogel carried on Stardust was exposed to the tail of comet Wild 2, and will have collected grains of dust from the comet, the solar environment, and possibly from extrasolar sources. If you're interested in helping find these grains, you can.

I'm completely serious. You want to do some actual astronomical work? Here's your chance. You can even get your name listed as a co-author of a scientific paper if the discovery of a dust grain you find is announced.
